1. Drink More Water
2. Eat More Fruits and Vegetables
3. Be More Active (even if it is Dance Dance Revolution)
4. Spend Less Time Online
5. Reduce Debt
If I can do these five things a little better (heck, one more glass of water a day - I hate drinking water), it should be a pretty good year.
And just for good measure:
6. Take a vacation. So needed.
